The dts for the CoreTile Express A15x2 A7x3 (TC2) only describes the PMUs of the Cortex-A15 CPUs, and not the Cortex-A7 CPUs. Now that we have a mechanism for describing disparate PMUs and their interrupts in device tree, this patch makes use of these to describe the PMUs for all CPUs in the system. For consistency, the existing A15 PMU interrupt-affinity property is reflowed across two lines.

This reverts commit 3d76be5b. The latest revision of Beaglebone Black does not support RTC-only mode. To avoid potential hardware damage, RTC-only mode was disabled by default by commit 7a6cb0ab ("ARM: dts: am335x-boneblack: disable RTC-only sleep to avoid hardware damage"). Unfortunately, an incorrect fix had already been applied, which instead of just disabling RTC-only mode, prevents the Beaglebone from powering down at all.

Commit 835a6a2f ("Bluetooth: Stop sabotaging list poisoning") thought that the code was sabotaging the list poisoning when NULL'ing out the list pointers and removed it. But what was going on was that the bluetooth code was using NULL pointers for the list as a way to mark it empty, and that commit just broke it (and replaced the test with NULL with a "list_empty()" test on a uninitialized list instead, breaking things even further). So fix it all up to use the regular and real list_empty() handling (which does not use NULL, but a pointer to itself), also making sure to initialize the list properly (the previous NULL case was initialized implicitly by the session being allocated with kzalloc()) This is a combination of patches by Marcel Holtmann and Tedd Ho-Jeong An.

Pull SCSI target updates from Nicholas Bellinger: "It's been a busy development cycle for target-core in a number of different areas. The fabric API usage for se_node_acl allocation is now within target-core code, dropping the external API callers for all fabric drivers tree-wide. There is a new conversion to RCU hlists for se_node_acl and se_portal_group LUN mappings, that turns fast-past LUN lookup into a completely lockless code-path. It also removes the original hard-coded limitation of 256 LUNs per fabric endpoint. The configfs attributes for backends can now be shared between core and driver code, allowing existing drivers to use common code while still allowing flexibility for new backend provided attributes. The highlights include: - Merge sbc_verify_dif_* into common code (sagi) - Remove iscsi-target support for obsolete IFMarker/OFMarker (Christophe Vu-Brugier) - Add bidi support in target/user backend (ilias + vangelis + agover) - Move se_node_acl allocation into target-core code (hch) - Add crc_t10dif_update common helper (akinobu + mkp) - Handle target-core odd SGL mapping for data transfer memory (akinobu) - Move transport ID handling into target-core (hch) - Move task tag into struct se_cmd + support 64-bit tags (bart) - Convert se_node_acl->device_list[] to RCU hlist (nab + hch + paulmck) - Convert se_portal_group->tpg_lun_list[] to RCU hlist (nab + hch + paulmck) - Simplify target backend driver registration (hch) - Consolidate + simplify target backend attribute implementations (hch + nab) - Subsume se_port + t10_alua_tg_pt_gp_member into se_lun (hch) - Drop lun_sep_lock for se_lun->lun_se_dev RCU usage (hch + nab) - Drop unnecessary core_tpg_register TFO parameter (nab) - Use 64-bit LUNs tree-wide (hannes) - Drop left-over TARGET_MAX_LUNS_PER_TRANSPORT limit (hannes)" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (76 commits) target: Bump core version to v5.0 target: remove target_core_configfs.h target: remove unused TARGET_CORE_CONFIG_ROOT define target: consolidate version defines target: implement WRITE_SAME with UNMAP bit using ->execute_unmap target: simplify UNMAP handling target: replace se_cmd->execute_rw with a protocol_data field target/user: Fix inconsistent kmap_atomic/kunmap_atomic target: Send UA when changing LUN inventory target: Send UA upon LUN RESET tmr completion target: Send UA on ALUA target port group change target: Convert se_lun->lun_deve_lock to normal spinlock target: use 'se_dev_entry' when allocating UAs target: Remove 'ua_nacl' pointer from se_ua structure target_core_alua: Correct UA handling when switching states xen-scsiback: Fix compile warning for 64-bit LUN target: Remove TARGET_MAX_LUNS_PER_TRANSPORT target: use 64-bit LUNs target: Drop duplicate + unused se_dev_check_wce target: Drop unnecessary core_tpg_register TFO parameter ...
